Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449276, here are decompositions:

13 + 31449263 = 31449276
17 + 31449259 = 31449276
29 + 31449247 = 31449276
43 + 31449233 = 31449276
97 + 31449179 = 31449276
113 + 31449163 = 31449276
149 + 31449127 = 31449276
193 + 31449083 = 31449276

Showing the first eight; more decompositions exist.
